摘要：A homologous series (C10, C12, C14, C16, C18) of synthetic O -alkyl and S -alkyl ethers of glycerol was analyzed by gas-liquid chromatography (GLC) and thin-layer chromatography (TLC), and examined by IR and n.m.r. spectroscopy; the physical properties of the O -alkyl and S -alkyl ethers were compared. Isopropylidene derivatives of the glycerol ethers and thioethers were quantitatively analyzed by GLC on polar and nonpolar liquid phases. On a medium polar liquid phase (ethylene glycol succinate), mixtures of the O -alkyl and S -alkyl ethers were completely resolved. Isopropylidene derivatives of glycerol ethers and of thioethers could be separated as classes (though not into individual homologues) by TLC. O -hexadecyl and S -hexadecyl ethers of glycerol are easily distinguished by IR and n.m.r. spectroscopy.
